I am trying to use the movie2avi function in MATLAB. I simply copy the sample program in my MATLAB R2015a:

nFrames = 20;
% Preallocate movie structure.
mov(1:nFrames) = struct('cdata', [],...
                        'colormap', []);
% Create movie.
Z = peaks; surf(Z); 
axis tight manual
set(gca,'nextplot','replacechildren');
for k = 1:nFrames 
     surf(sin(2*pi*k/20)*Z,Z)
     mov(k) = getframe(gcf);
end
% Create AVI file.
movie2avi(mov, 'myPeaks.avi', 'compression', 'None');

But an error message appears:

Error using avi
Unexpected Error. Reason: Failed to open file.
Error in audiovideo.internal.aviwriter (line 168)
              aviobj.FileHandle = avi('open',filename);
Error in movie2avi (line 63)
avimov = audiovideo.internal.aviwriter(filename,varargin{:});
Error in MakeMovie (line 36)
movie2avi(mov, 'myPeaks.avi', 'compression', 'None');

What's wrong here? Please help.

Can you check if the location you are attempting to write the file to has write permissions?

movie2avi is being deprecated. I would recommend using VideoWriter as it allows you the use of more modern compression methods such as MPEG-4, MJ200), MJPEG AVI.

See VideoWriter documentation for examples.

Hope this helps.
